Routine experiment attempted: runaway reaction & nuclear meltdown. 30 km dead zone, 10000"s casualties: largest nuclear incident of all time, poor training, design flaws and safety systems ignored or turned off, canada has had 2 smaller incidences. One hour earlier an inspector picked up concrete debris under the bridge. In may 2005, overpass fully inspected and given a clean bill of health. In 2000,another bridge in laval collapsed, killing 1. What is unfortunate is we built and built and built without thinking we"re going to have to maintain it . It is safe if the risks" are judged acceptable: this judgement can be formalized laws/reg"ns, this judgement is not always formalized you! The overriding aim is to protect public safety. A hazard is the consequence of an event: disease, natural, technological failure, accidents, sociopolitical, etc . Weighing the risk vs. hazard (i. e. potential versus consequence)
